SMOKE-CONSUIVIING DEVICE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 2, 1904. Serial No. 205,887.

1' (17/ (1'71 out it may cancer/2 Be it known that l, RICHARD riton, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a new and useful Improvement in Smoke-Consuming Devices; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the construction and attachments to locomotives by which the unconsumed products of combustion may be controlled and delivered back to the furnace and thoroughly consumed. Secondly, I provide to control the products by the exhaust from the cylinders and mingle the exhauststeam with the carbonous gases to effect a combustible gas that will readily consume. Further, with the device in use I prevent the exhaust and gases from passing from the locomotive, which to a certain extent checks the dirt nuisance. This principle adapted to locomotives will act as an induced draft and smoke-consumer.

In the drawing I show a side elevation of a section of a locomotive, showing my invention in position.

Like letters refer to like parts throughout the specification and drawing.

In the drawing, 11' represents the boiler, 71 the smoke-arch, (Z the steam-chest, and e the chimney or stack, all of the parts being the same as arranged in all ordinary locomotives, and I make no changes or alterations to the parts in carrying my invention into effect.

Formed through the back part of the chimney is an opening f, which may be circular, square, or of any suitable shape. Coupled to the chimney and adapted to communicate with the opening f is a tubular connection g. The tubular connection may consist of a pipe or a tubing of a similar shape as the openingf': but for all practical purposes and to describe the nature of the device I will term it circular in cross-section. The tubular connection g extends rearwardly from the chimney a, parallel with the boiler as far back as possible, thence it is curved downward and rearward, conforming with the symmetry of the boiler, then under and through a circular opening /1. into the ash-pit I; of the furnace j. Surrounding the connection 9 adjacent to the opening /i. is a circular flange it to prevent the end projecting in too far and make a tight fitting and by which the end will be held fast to the furnace by bolts or rivets.

The exhaust-pipes from the steam-chests 6! pass upward through the smoke-arch7; and terminate in a single discharge-pipe bent at right angles and passed through the opening 7" in the chimney c and discharges into the tubular connection 7.

The diseharge-pipel terminates in a pointed nozzle m, and as the exhaust-steam passes through the nozzle into the pipe 4/ it creates a suction and effects a vacuum and draws the unconsumed carbon and gases from the chimney and smoke-arch into the pipe 1/ through the openingfand forces them through the con nection into the furnace j, where they mingle with the products of combustion and are thoroughly consumed, thus saving considerable fucl and acting as a smoke consumer as well.

Arranged in the connection (7 in proximity with the location of the nozzle 12. is a damper n, constructed and adapted to be operated by a connecting-rod carried to the cab of the engine, so as to be operated and adjusted by the engineer or fireman. The damper is so arranged that it may be regulated to admit any desired amount of oxygen to be drawn in to mix with the combustible gases drawn from the fine and while being forced through the connection to the furnace.

Situated in any convenient position within the furnace is a relief-pipe 1). One end of the pipe is set in the furnace and is provided with a funnel-shaped mouth r. Theother or discharge end is carried upward and ends at an elevation in alinement with the chimney (a.

Arranged in the pipe p in any suitable position between the two ends is a damper s, connected with an operating-rod 2f, carried and ending in the cab of the engine, where it may be operated by the engineer or fireman. The purpose of the relief-pipe is that times where the engine is required to expend extra energy and extra steam is turned on the superfluous exhaust that is forced through the connection r to the furnaccj may be carried off through the pipe by the opening of the damper s.

The operation of the device is as follows: The products of combustion consisting of the unconsumed carbon pass from the furnace through the boiler-tines to the smoke-arch, where they pass upward to the chimney, where they are then sucked through the opening f in the side of the chimney by the suc tion effect of the exhaust steam escaping through the nozzle of the exhaust-pipe into the tubular connection 5 Oxygen may then be admitted into the connection 9, through the damper n, to miX with the carbonous gases and all be forced back into the furnace through the connection 9 by the pressure of the exhaust-steam. It will be readily understood that the pressure on the furnace and the amount of gases to be consumed may be regulated by the relief-pipe p, communicating with the furnace, as the mouth of the reliefpipe will be arranged in close proximity with the inlet of the tubular connection g to the furnace, and the dampers in the relief-pipe 39 may be regulated so that all or any amount of the gases may pass off before passing to the fire.

l/Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a smoke-consuming device for locomotives, the combination of a stack provided with an opening in its side, a smoke-pipe or tubular connection leading from said opening to the ash-pit, said pipe provided with an airinlet, a damper controlling said air-inlet, an operating-rod for said damper leading to the cab, an exhaust-steam pipe leading from the cylinders through the smoke-box and the stack, said pipe terminating in a nozzle projecting into the smoke-pipe, a pressure-relief pipe leading from the ash-pit in close proximity to the smoke-pipe, a damper in said pipe, and an operatingrod for said damper leading to the cab, substantially as described.

2. In a smokeconsuming device for locomotives, the combination of a stack provided with an opening in its side, a smoke-pipe or tubular connection leading from said opening to the ash-pit, a pressure-relief pipe leadingfrom said ash-pit in close proximity to the outlet end of smoke-pipe, an exhaust-steam pipe leading from the cylinders through the smoke boX and stack, and terminating in a pointed nozzle projecting into the said smokepipe, a damper-controlled inlet in said smokepipe, an operating-rod for said damper leading to the cab, a damper in said pressure-re lief pipe, an operating-rod for said damper leading to the cab, the said exhaust-steam pipe adapted to suck in and force the products through the said smoke-pipe, the said pressure-relief pipe adapted to carry off any or all of the said products from the said smokepipe and furnace, substantially as described.
